Failure to follow the warnings and instructions may result in electric shock, fi re and/or serious injury. Save all warnings and instructions for future reference. The term power tool in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. 1) Work area safety a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. 2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any way. 26

27 English Do not use any adapter plugs with earthed (grounded) power tools. Unmodifi ed plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. 3) Personal safety a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c) Prevent unintentional starting. Ensure the switch is in the off position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your fi nger on the switch or energising power tools that have the switch on invites accidents. d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. 27

28 English 4) Power tool use and care a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power toolʼs operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. 5) Battery tool use and care a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fi re when used with another battery pack. b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fi re. c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fi re. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns. 6) Service a) Have your power tool serviced by a qualified repair person using only identical replacement parts. 28

29 This will ensure that the safety of the power tool is maintained. 29 English CAUTION Keep children and infirm persons away. When not in use, tools should be stored out of reach of children and infirm persons. SHRUB SHEAR SAFETY WARNINGS Keep all parts of the body away from the cutter blade. Do not remove cut material or hold material to be cut when blades are moving. Make sure the switch is off when clearing jammed material. A moment of inattention while operating the shrub shear may result in serious personal injury. Carry the shrub shear by the handle with the cutter blade stopped. When transporting or storing the shrub shear always fit the cutting device cover. Proper handling of the hedge trimmer will reduce possible personal injury from the cutter blades. Keep cable away from cutting area. During operation the cable may be hidden in shrubs and can be accidentally cut by the blade. GRASS SHEAR SAFETY WARNINGS IMPORTANT READ CAREFULLY BEFORE USE KEEP FOR FUTURE REFERENCE Safe operation practices Training a) Read the instructions carefully. Be familiar with the controls and the proper use of the machine. b) Never allow people unfamiliar with these instructions or children to use the machine. Local regulations can restrict the age of the operator. c) Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.

(off for 0.1 seconds) Insert Hole for connecting the rechargeable battery Pilot lamp Fig. 3 Battery overheated. Unable to charge (Charging will commence when battery cools). Malfunction in the battery or the charger. (2) Regarding the temperatures of the rechargeable battery The temperatures for rechargeable batteries are as shown in the Table 2, and batteries that have become hot should be cooled for a while before being recharged. Table 2 Recharging ranges of batteries Rechargeable batteries Temperatures at which the battery can be recharged BCL C 50 C 36

37 37 English (3) Regarding recharging time Depending on the combination of the charger and batteries, the charging time will become as shown in Table 3 Table 3 Charging time (At 20 C) Charger UC10SFL Battery BCL1015 Approx. 40 min. NOTE The charging time may vary according to temperature and power source voltage. 4. Disconnect the charger s power cord from the receptacle. 5. Hold the charger fi rmly and pull out the battery. NOTE Be sure to pull out the battery from the charger after use, and then keep it. Regarding electric discharge in case of new batteries, etc. As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the fi rst and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 3 times. How to make the batteries perform longer (1) Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter. (2) Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while. CAUTION If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (off for 0.5 seconds). In such a case, first let the battery cool, then start charging. When the pilot lamp flikers (at 0.2-second intervals), check for and take out any foreign objects in the charger s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center. Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC10SFL is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

Pin Center hole Fig. 16 Crank cam holder Fig. 17 Screw Bottom plate Fig. 18 HOW TO USE WARNING To prevent accidents, make sure there are no people in the work area. Keep your hands and all parts of the body away from the blade to prevent contact that could lead to injury. Use protective goggles during work to prevent injury from twigs and wood chips. Do not use to tool to cut wire, metal plates or other hard objects. The tool could be damaged and cause injury. 41

42 English 1. Trimming hedges and garden trees [Shrab shear] CAUTION Use a pair of pruning shears to cut thick branches before using the shrub shear. Do not force the tool to prevent it from breaking. Stop the tool immediately if the blade stalls against a too heavy branch. Do not allow the motor to seize up as it could damage the motor. Use a sturdy ladder or step ladder when cutting tall garden trees. Use only for cutting shrub. (1) Clear the area around the garden tree you want to prune and set up a stable platform to work from. (2) Place the blade in the blade case to prevent accidental contact. (3) Install the battery in the tool. (4) Press the Lock Off button and pull back the switch to start trimming. NOTE Lubricate (using sewing machine oil, mineral oil, etc.) the blade before starting and then every hour. Use an adequate amount of oil and wipe away excess oil. During work (for example, when taking rests) do not leave the tool in a place exposed to direct sunlight or high temperature. This will prevent proper cooling and could result in damage. Do not use the tool for work that exceeds its capacity. Such operation could cause the motor to lock up or slow down and will damage it. Trimming garden trees Use a pair of pruning shears to remove 10 cm of branches that are 8 mm or thicker so that they do not interfere with trimming. (Fig. 19) Fig. 19 Trees with luxuriant foliage should be trimmed starting from the bottom and work up to achieve the desired shape. (Fig. 20) Fig

43 English Trimming hedges Trim the top of hedges by moving the tool from right to left (or left to right) and trim the sides by starting from below and working up. (Fig. 21) Fig. 21 NOTE Do not use the tool for cutting the lawn or weeds. Grass or weeds could stick to the blade. Cut thick branches by gently pressing the blades against the branch. 2. Trimming lawns [Grass shear] CAUTION Use only for cutting grass. Stop the tool immediately should gravel or branches enter the blade during trimming and remove the battery. Do not allow the motor to seize up as it could damage the motor. Use a pair of tongs to gently remove gravel from the blade. To prevent injury, keep hands, fingers and other body parts away from the blade. (1) Remove gravel and branches from the lawn to be trimmed. (2) Place the blade in the blade cover to prevent accidental contact. (3) Install the adjuster when required to adjust trimming height. (4) Install the battery in the tool. (5) Press the Lock Off button and pull the switch to start trimming. Place the tool on the lawn and slide the tool forward. (Fig. 22) NOTE Fig. 22 Lubricate (using sewing machine oil, mineral oil, etc.) the blade before starting and then every hour. Use an adequate amount of oil and wipe away excess oil. During work (for example, when taking rests) do not leave the tool in a place exposed to direct sunlight or high temperature. This will prevent proper cooling and could result in damage. Do not use the tool for work that exceeds its capacity. Such operation could cause the motor to lock up or slow down and will damage it. Do not lower the front end of the blade to prevent sand, gravel or soil from entering the blade and damaging it by making it less sharp. Trimming tall grass Attempting to cut tall grass at one go will expose the blade to excessive load and wear the blade. First remove 1/3 of the height starting from the top before trimming it to the desired height. 43

44 English Trimming around stone walls and curbs When trimming around curbs, move the blade sideways along the curb. (Fig. 23) This makes it possible to trim without leaving untrimmed edges. 3. Continuous operating time Approx. 30 minutes (depending on the work conditions) MAINTENANCE AND INSPECTION Fig. 23 WARNING Be sure to turn the tool off and remove the battery from the tool before making inspections or carrying out maintenance. Do not disassemble to blade. Failure to heed this warning may result in injury. Use gloves, or cloth to protect your hands when handling the blade. Failure to heed this warning may result in injury. 1. Sharpening the blade (Fig. 24) Move an iron fi le in the direction of the arrow for a rough sharpening then use an oil stone to give the blade a good fi nish. (1) Use a fi ne iron fi le or one of intermediate coarseness. (2) Coat the oil stone with machine oil (bicycle oil or the like). (3) Use a whetstone to gently remove any burrs from the back of the blade edge. When to sharpen the blade Surface to be ground While this will vary the type of trees that are trimmed and how often it is used, it is a good idea to sharpen the blade about once a year to maintain a sharp edge. NOTE Do not use water for cleaning the blade to prevent rust or other damage. 2. Lubricating the blade During trimming, sap adhering to the blade edge will increase load and wear down the battery more rapidly. Use machine oil (or bicycle oil or the like) to lubricate the blade and wipe the blade with a cloth. To prevent the blade from rusting, be sure to lubricate the blade after use and when it will not be used for an extended period of time before placing it in the blade case. 3. Inspecting the mounting screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard. 44 Blade Surface to be ground Fig. 24

45 English 4. Maintenance of the motor The motor unit winding is the very heart of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water. 5. Cleaning on the outside When the power tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics. 6. Storage Store the power tool in a place in which the temperature is less than 40 C and out of reach of children. 7. Service parts list CAUTION Repair, modification and inspection of Hitachi Power Tools must be carried out by a Hitachi Authorized Service Center. This Parts List will be helpful if presented with the tool to the Hitachi Authorized Service Center when requesting repair or other maintenance. In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed. Important notice on the batteries for the Hitachi cordless power tools Please always use one of our designated genuine batteries. We cannot guarantee the safety and performance of our cordless power tool when used with batteries other than these designated by us, or when the battery is disassembled and modifi ed (such as disassembly and replacement of cells or other internal parts). 45

46 English TROUBLESHOOTING Use the inspections in the table below if the tool does not operate normally. If this does not remedy the problem, consult your dealer or the Hitachi Authorized Service Center. Symptom Possible cause Remedy Charger Tool The Charge lamp does not go on. The Charge lamp does not go off after 4 hours of charging. Does not operate. The power plug is not connected to an AC outlet. The battery is not properly connected to the charger. The battery or charger electrodes are soiled. The battery is extremely hot. The battery or charger is faulty. The battery is depleted. (The battery level warning lamp does not go on.) The battery has not been properly installed. The blade has been incorrectly installed. Connect the power plug to an AC outlet. Insert the battery so that it is properly seated in the charger. Use a cotton swab or other tool to clean the electrodes. Allow the battery to properly cool before charging. Disconnect the power plug and consult your dealer or the Hitachi Authorized Service Center. When a storage battery with little power left is not used for an extended period of time, battery power may drop so low that it cannot turn on the battery level warning lamp. Charge the battery. Remove the storage battery from the battery compartment in the tool and check for foreign matter. Also check the battery electrodes for soiling. Make sure that the battery is pressed in until it clicks into place. If the blade does not move but the motor is turning, the blade has probably been incorrectly installed. Make sure that the crank holder and crank cam has been installed. 46

47 Tool Symptom Possible cause Remedy Foreign matter is lodged in the blade. Does not operate. The tool does not trim well. The tool has been used for heavy work. The Lock Off button was not pressed when the switch was pulled back. The blade has become dull. [Shrub shear] The blade stopped because it was used to cut a branch whose width exceeded the blade s cutting capacity. NOTE Work that will repeatedly cause the blade to stop will eventually damage the motor. English When there is foreign matter in the blade, remove the battery and use a pair of tongs or similar tool to remove it. Take great care since the tool may start operating when the foreign matter has been removed. Sap or rust may also prevent the blade from operating. Use a wire brush or similar tool to remove sap or rust. This is the effect of a function that protects the battery by turning off the motor when the tool is exposed to an excessive load. Release the switch and remove what caused the excessive load and pull back the switch to resume work. To prevent accidents from incorrect operation, the Lock Off switch must be pressed while the switch is pulled back to start the motor. Use a wire brush or other tool to remove sap and rust and use a fi le or whetstone to sharpen the blade. If these efforts fail to make the blade sharper, the blade has reached the end of its service life. Replace the blade with a new one. Some garden trees have wood that is very hard and may be beyond the capacity of the tool even if it is of a width that is within normal capacity. Use a pair of pruning shear to remove thick branches before starting work. An oblique cut may also exceed the capacity of the tool since the length of the cut increases. Be sure to trim thick branches at right angles. 47
